Subject: [RFC PATCH v3 net-next 04/24] net: ocelot: fix switchdev objects synced for wrong netdev with LAG offload
Date: Mon, 12 Jul 2021 18:21:22 +0300	[thread overview]
Message-ID: <20210712152142.800651-5-vladimir.oltean@nxp.com> (raw)
In-Reply-To: <20210712152142.800651-1-vladimir.oltean@nxp.com>

The point with a *dev and a *brport_dev is that when we have a LAG net
device that is a bridge port, *dev is an ocelot net device and
*brport_dev is the bonding/team net device. The ocelot net device
beneath the LAG does not exist from the bridge's perspective, so we need
to sync the switchdev objects belonging to the brport_dev and not to the
dev.

Fixes: e4bd44e89dcf ("net: ocelot: replay switchdev events when joining bridge")
